Japan alleges offensive by South Korea in new video escalating tensions

Japan has released video footage to prove that a South Korean warship allegedly locked its fire-control radar onto a Japanese warplane off the country's northern coast, the latest move in an escalating row between the two Asian neighbours. The Defense Ministry's 13-minute video published on its website Friday contained Japanese crewmembers' voices asking the destroyer for clarification but getting no response.

Japan alleges that last week a South Korean destroyer repeatedly locked its target illumination radar on the Japanese aircraft off Japan's northern coast. A lock with a fire-control radar is considered a hostile act, and Japan has protested. Seoul has denied the allegation, saying its warship used an optical camera while rescuing a North Korean fishing boat in distress. Tokyo and Seoul are also disputing Japan's war compensation.
